Abstract: PROBLEM TO BE SOLVED: To obtain a conjugate filament having high nitrile content, excellent in processability and useful for woven or knitted fabric, nonwoven fabric, or the like by including plural specific polymers arranged in core-sheath configuration. SOLUTION: This conjugate filament having high nitrile content comprises two or more kinds of polymers arranged in sheath/core configuration. The sheath polymer is selected from the group consisting of an acrylonitrile olefinic unsaturated polymer composed of 50-95 wt.% acrylonitrile monomer and 5-50 wt.% olefinic unsaturated monomer such as methyl methacrylate, an organic polymer such as a polypropylene and a combination thereof. The sheath component content is 99-1%, preferably 90-10% based on the filament. The core polymer is selected from the group consisting of the above acrylonitrile olefin-based unsaturated polymer, the above organic polymer and a combination thereof, but the core polymer is different in the composition from the sheath polymer. The core component content is 1-99%, preferably 10-90% and is thermally stable.

Abstract: PROBLEM TO BE SOLVED: To provide a multi-layer structure with different organic polymer layers containing, in detail, a typical organic polymer layer and an acrylonitrile olefinic unsaturated polymer which contains no solvent nor water and can be melt-processed, and a multi-layer preparation method. SOLUTION: This multi-layer structure is formed of a layer containing an organic polymer composition and a layer containing an acrylonitrile olefinic (olefinically) unsaturated polymer which contains no solvent nor water and can be melt-processed. The unsaturated polymer contains about 50-95 wt.% of polymerizable acrylonitrile monomer and about 5-50 wt.% of at least, one kind of polymerizable olefinic unsaturated monomer. The organic polymer and the acrylonitrile olefinic unsaturated polymer are thermally stable to each other.
